The invention is directed to the field of acoustic shells, and more specifically, to moveable acoustic shells that are configured and designed for improved operability and compatibility with emergency systems.
Acoustic shells are physical structures designed to capture sound produced in a performance area of a performance arts venue and to project the sound into an audience area of the venue. Many indoor performance settings, such as, for example, concert halls, auditorium or gymnasiums, the acoustics are less than ideal. In such indoor performance settings, an acoustical shell can help overcome the acoustical shortcomings of the performance area by keeping the sound from being lost to the sound-absorbing regions above the performance area, thereby allowing the performers to hear themselves better so that they can project a better blended sound to the audience. Acoustic shells are therefore found in a wide variety of performing arts venues, such as for example, school auditoriums, concert halls, theater houses and outdoor stages.
The acoustic shell encloses portions of the performance area with a back wall, side walls, and a canopy (above the performance area). Such an acoustic shell acts in some ways like a megaphone or bull horn, with sound produced at the narrow end of the megaphone (the rear of the acoustic shell) and emitted towards the audience at the wider of the megaphone (the wider front of the shell). In addition to outward sound projection, acoustical shells enable the individual performers to hear themselves and those around them so that they can make any necessary adjustments for intonation purposes without having to force their volume output in order to be heard.
Since venues are often designed to host a variety of different performances, some requiring an acoustic shell and some not, many venues use removable or movable acoustic shells. For instance, large auditorium style venues are commonly used to host both orchestra concerts, which generally require an acoustic shell, and theatrical productions, which generally do not. Accordingly, auditorium style venues typically provide removable acoustic shells to facilitate both types of performances.
Removable acoustic shells are conventionally formed by combining a collection of independent components within the stage area of a performing arts venue. For instance, the walls of a conventional removable acoustic shell may be formed by placing a number of panel sections side by side on the stage, while the ceiling of the conventional removable acoustic shell is formed by hanging panel sections from the stage rigging.
Unfortunately, these conventional removable acoustic shells have several shortcomings. These shells are generally cumbersome and require a significant amount of time and labor to set up and take down, which can prevent the stage from being usefully employed for rehearsals or additional performances. More critically, these shells were designed with portability and acoustics in mind, and are not designed to also consider emergency situations and the need to work with existing emergency systems, such as sprinkler systems. Indeed, even more troubling is that conventional acoustic shells would likely impede or completely block such systems by preventing water flow underneath, and may collect water which creates an additional hazard.
Accordingly, there is a need in the art for acoustic shells which can perform the functions needed of an acoustic shell while also ensuring the operability of existing emergency systems and the safety of the performers and members of the audience.
The invention is generally directed to systems which resolve the issues cited above as well as others in the art.

While the disclosure concludes with claims particularly pointing out and distinctly claiming specific embodiments, various features and advantages of embodiments within the scope of this disclosure may be more readily ascertained from the following description when read in conjunction with the accompanying drawings, in which:
It should understood that the invention is generally directed to systems, methods and apparatus for providing and operating an acoustic band shell assembly within or outside of a building structure which may have fire and other emergency systems.
An embodiment of the acoustic shell assembly constructed according to the invention is illustrated in
Frame 102 is further includes laterally-spaced beams 106 and support members or arms 108 for suspending frame 102 from the ground, walls, ceiling or stage rigging pipe battens (not shown). In the exemplary embodiment frame 102 is suspended from one or more stage rigging pipe battens by arms 108 being secured therein. Beams 106 may further include lighting fixtures (not shown) installed in openings 110.
Each beam 106 is spaced laterally from an adjacent beam 106 to form an open frame section 112 between each set of laterally adjacent beams 106. Each panel 104 is cooperatively supported in the open section 112 between the set of laterally-spaced beams 106. In this embodiment of assembly 100, two panels 104 (also referred to herein as 104a and 104b for ease in illustration) are mounted between each set of laterally-spaced beams 106 and within each open frame section 112. It should be understood that while panels 104 are depicted as rectangular in shape, each panel may be of other shapes as well such as circular or octagonal.
In this embodiment, each panel 104 has rods 114 protruding from opposing panel lateral sides 116 which facilitates mounting panel 104 to laterally-spaced beams 108 and enabling panels 104 to freely rotate from closed and open conditions between beams 108. Rod 114 may further include a spring 124 thereon to maintain panel 104 in position within section 112 between lateral beams 106.
Adjacent panels 104a,b are configured to engage one another to maintain each set of panels 104a,b in the closed condition. The closed condition of panels 104a,b may be maintained by various engagement means such as an engagement of rods 114 to restrict rotational motion of panels 104. In this embodiment, inner facing sides 118 and 120 of respective adjacent panels 104a,b mounted between a set of beams 106 include elements or parts which cooperate to provide an engagement mechanism 122 for forming a non-permanent engagement of adjacent panels in the closed condition.
In this embodiment, panels 104 will freely rotate into, and come to rest in, the open condition when not engaged by engagement mechanism 122 and maintained in the closed condition. In some embodiments, the rotational motion of panels 104 is driven by a force applied on the panel or a bias of the panels. In the exemplary embodiment of the invention, rods 114 are mounted on panels 104 to be in an offset position relative to the center of gravity of each panel 104, thus actuating the free rotation of the panel in a desired direction (that is, rotating in the direction of the portion of the panel on either side of rods 114 having the greater weight) by virtue of gravitational forces applied on the panel 104 when the engagement of mechanism 122 is disengaged.
The non-permanent engagement of mechanism 122 may be created by any suitable engagement device which is configured to be engaged and disengaged in response to a triggering event. In the exemplary embodiment, the engagement mechanism 122 comprises an electromagnetic engagement which includes cooperating parts on inner facing sides 118 and 120 of adjoining panels 104a,b, such as singular magnetic engagement members 122a and 122b, to establish an engagement of sufficient strength to hold adjacent panels 104 in the closed condition. The engagement may be formed by supplying electrical current to mechanism 122 through wiring provided along the beams 106 and panels 104, or multi-conductor cables suspended from the ceiling connected to mechanism 122.
In some embodiments a triggering event for causing the disengagement of panels 104 via the deactivation of the electromagnetic engagement formed by mechanism 122 may be the result of the electrical supply to the engagement being terminated. Upon being disengaged, the bias created by the offset rod positioning takes over and the adjacent panels 104 rotate into the open condition. The engagement of each disengaged panel 104 may be resumed by rotating the disengaged panels 104 about their respective axes until the engagement members 122a and 122b on the inner facing sides 118 and 120 contact one another. Provided that the electrical supply to the electromagnetic engagement is turned on, the engagement between the adjacent panels 104 will resume.
In use, the electromagnetic engagement of the invention may be in communication with a fire alarm system, such as a building fire alarm, rate of rise detectors or fusible links which will provide the triggering event, such as by automatically stopping the supply of electricity, including the supply of electricity to the electromagnetic engagement as is routine upon activating the sprinkler system and roof hatches. The disengaged panels 104 of this embodiment then rotate into the open condition, which advantageously enables the sprinkler system to direct water through the transversely positioned panels 104 of the acoustic shell ceiling assembly 100.
In the exemplary embodiment each beam 106 of frame 102 is hingedly mounted to arms 108 by pivoting arms 126 and 128 which enables beams 106, including the engaged adjacent panels 104, to be pivoted from a generally perpendicular position relative to arms 108 as shown in
The acoustic shells of the invention can have a variety of different forms and features. It should be understood that the panels and/or beams and other support members may be constructed of a variety of materials. For example, the panels and beams can be formed of materials, such as wood, plaster, metal, gypsum, and fiberglass, and include a coating. Further, the panels and beams can be in various shapes, such as rectilinear shapes as in a shelled room, or curved shapes as in a shelled semi-dome. Moreover, the assembly of the invention can be formed as either permanent fixtures or fully removable parts of the venues in which the invention is used.
While exemplary apparatus, systems and methods of the invention have been described herein, it should also be understood that the foregoing is only illustrative of a few particular embodiments with exemplary and/or preferred features, as well as principles of the invention, and that various modifications can be made by those skilled in the art without departing from the scope and spirit of the invention. Therefore, the described embodiments should not be considered as limiting of the scope of the invention in any way. Accordingly, the invention embraces alternatives, modifications and variations which fall within the spirit and scope of the invention as set forth herein, in the claims and any equivalents thereto.
